Q:Shandong foundry, casting small pieces of precision casting
Dongying Huayang precision casting factory, the smallest to do 2G pieces.
Q:How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.
Q:How to calculate the price of casting parts?
Cost of raw materials + electricity (fuel) costs + workers' wages + managers' wages + transport costs + raw materials burned + accessories costs + equipment maintenance depreciation costs + management fees + tax. The most convenient, the raw material market price plus 2000 yuan, plus you want profits on the line.
Q:How much is the amount of electrophoretic paint per square meter used in the casting?
It was a very simple question, and it was complicated by what you said.
Q:What is the difference between casting and stamping parts?
Separation process is also called blanking, the purpose is to make the stamping parts along a certain contour line from the sheet metal separation, at the same time guarantee the quality requirements of the separation section. Stamping is a highly efficient production methods, the use of compound die, especially the multi station progressive die stamping process can be completed in a multi machine, realized by belt uncoiling, leveling, punching, forming and finishing automatic production. High production efficiency, good working conditions, low production costs, can produce hundreds of parts per minute.
Q:Which surface is coarser for cast iron or cast steel castings? Why?
Roughness mainly depends on the surface roughness on the surface of the sand.
Q:How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.
I am doing this for sale, if the price is mainly based on the product structure, the difficulty of pricing. At present, if it is more formal and material guarantee manufacturers generally in 48-53 yuan /Kg (of course, products have a certain weight, such as greater than 100g), our company's current price of about 53 yuan /Kg or so. .
Q:Where is the precision casting factory?
Shandong, DongyingThe birthplace of precision casting
Q:Heat treatment process and purpose of casting parts
Natural aging (also known as Chang Hua): lost in the open, the sun and rain, can have experienced years of wind and frost.
Q:How to distinguish the forging parts and casting parts accurately
To distinguish from the use of materialsForging materials are mainly made of carbon steel and alloy steel of various components, followed by aluminum, magnesium, titanium, copper and their alloys. The original state of the material is rod, ingot, metal powder and liquid metal. The materials needed for casting are mostly metal, wood, fuel, molding materials and so on. In contrast, the forging parts rarely produce dust, harmful gas and noise, etc., and play a more obvious role in environmental protection. Of course, because of this, the price of forged parts on the market is higher than that of castings.
